FASTENING THE BURNER TO THE BOILER
The burner must be applied to the boiler's iron plate, where the
stud bolts given as standard accessories have been already fitted
in accordance with the plate drilling. It is advisable to electrically
weld the stud bolts to the internal part of the plate to avoid extrac-
ting them together with the unit's locking nuts, should the burner
be disassembled.
If the plate is not supplied with heat insulation, it is necessary insert
an insulating protection at least 10 mm. thick between the plate and
the boiler. To fit the insulating flange between the burner and the
boiler plate, remove the end section of the combustion head.
Ensure that the combustion head enters the furnace to the extent
specified by the boiler manufacturer.
(The flange used to fasten the burner to the boiler can be moved
along the combustion head in order to allow the combustion head
to enter the furnace to the extent required for the different types of
E
boiler).
When this operation has been carried out, connect the burner to the
N
light oil pipeline, as illustrated in our drawings. The burner can be
supplied with a normal head or a long head on request.

ELECTRICAL CONNECTIONS

L
It is advisable to make all connections with flexible electric wire.
I
The electric lines should be at an adequate distance from hot parts.
S
Make sure that the electric line to which the unit will be connected
has frequency and voltage ratings suitable for the burner. Check
H
that the main line, the relevant switch with fuses (essential) and the
current limiter (if required) are capable of withstanding the maximum
current absorbed by the burner.
For details, refer to the specific electric diagram for each single
burner.
FUEL FEED SYSTEM (LIGHT OIL)
The burner pump should receive fuel from a feed circuit which has
an ancillary pump and, in some cases, a pressure regulator capable
of modifying the pressure value 0,2 to 1 bar (see drawing 8575/1).
In this case, the value of the fuel feed pressure at the burner pump
(0,2 ÷ 1 bar) should not vary when the burner is at a standstill or
when it is operating at the maximum fuel delivery required by the
boiler.
Normally it is possible to realize a circuit without a pressure regulator
as shown in drawing n° BT 8666/3.
The feed circuit must be realized according to drawing 8575/1 or
to drawing 8666/3.
The dimension of the pipelines should be in function with their length
and with the output of the pump utilized.
Our instructions cover the basic requirements needed to ensure
efficient operations. All rules and regulations existing in the country
of installation should be strictly complied with and the local fire
brigade should be consulted.
MOUNTING INSTRUCTIONS FOR ADJUSTABLE STAND
- Insert theadjustable stand in the hole located in the bottom
part of the burner case as shown in the sketch 0002934500.
